SPECIFICATION forming part of Letters Patent No. 329,282, dated October 2'7, 1885.

Application filed August 12, 1885. Serial No. 174,178. (No model.)

To all whom it may concern:

Be it known that we, GEORGE W. COPE- LAND, of Malden, in the county of Middlesex, and JOSEPH E. CRISP, of Boston, in the county of Suffolk, both in the Commonwealth of Massachusetts, citizens of the United States, have invented a new and useful Improvement in Lasting-Machines, of which the following is a full, clear, and exact description, reference being had to the following drawings, formingapart of this specification, in explaining its nature.

The invention is an improvement upon that described in the application for patent of George W. Copeland, executed July 30, 1885, Serial No. 173,352, and relates especially, first, to the jack-pin and means for adjusting its height'automatically and for locking it; second, to a gage for adjusting the height of the last with the inner sole and the upper thereon preparatory to the act of lasting its edge; third, to mechanism for leveling, compressing, and consolidating the turned-over upper upon the insole after it has been fastened, and, preferably, while it isheld by a lasting band or clamp, hereinafter specified; and, fourth, to the said ,lastingband or clamp and to the manner of supporting and operating the same.

p In the drawings the devices are represented as applied to a machine for lasting the heel of a boot or shoe.

Figure 1 represents a front elevation of such a machine. Fig. 2 is a view, part in vertical section and part in elevation, of the upper portion of the shoe, to represent the operation of the compressing device for leveling, flattening, and compressing the turned-over edge and forming a square smooth corner, as hereinafter specified. Fig. 3 is a detailed view, to which reference will hereinafter be made. Fig. 4 is a vertical central section of the machine from frontto rear. Fig. 5is a detailed view to represent the last-pin and its adjacent. parts. Fig. 6 is a horizontal section upon the line at w of Fig. 5. Figs. 7, 8, and 9 illustrate the operation of the lasting band or. clamp. Fig. 10 is a vertical section enlarged to show the operation of the leveling and compressing device, and Fig. 11 is a perspective View of the lasting band or clamp.

A is a column or post rising from the base a, and supporting the working devices. B B are the blocks carrying the breakdownirons b, and these blocks and the irons are like in construction and operation similar parts de scribed in the said application of George WV. Copeland-that is, the blocks B have an opening and closing movement, and the breakdown-irons have horizontal movements imparted to them.

The devices for providing the blocks and the irons with these movements are like those described in said application, and need be but briefly described here. The blocks B B are carried or supported by the table, which consists of the upper portion of the standard, and they are pivoted at If. They are moved horizontally by the combined lever and spring b toward the heel, which spring is operated by the vertically-movable cam orincline If. The jaws are closed by the combined side levers and springs, which are horizontally movable by the inclines or cams 1) b There is attached to the front edge of each of the jaws B B a metal band, 0, which is curved inward from the jaws to approximate the curve of the heel end of thelast, and it is shaped and supported, preferably, so 'as to be somewhat inclined, as represented in Figs. 2, 10, and 11. It is secured to the jaws B B by means of screws, or in any other desirable way,and it is adapted to be drawn against the heel end of the last by the horizontal movement of the jaws until its rear inner surface comes in contact with the surface of the upper at the extreme end of the heel of the last,(see Figs. 7 and 8,) and then by the closing-in movements of the forward ends of the blocks it is brought to bear continuously along the end of thelast on each side of the heel from the back to the shank, and the section of the upper with which it is brought in contact is held clamped against the surface of the last. (SeeFig. 9.) The band is also arranged so that its upper edge extends above the upper surface 'or level of the insole in order to provide an abutment or surface which shall develop or mark the line of the margin of the upper, and which shall hold it or conforming iron so that in the folding action the margin or edge folded in must creep or extend from that abutment or surface forward upon the surface of the insole, and thereby prevent any slack, at the same smooth corner. We prefer to use in connection with this band the breaking-down irons described in said application. When they are so used, they are caused to be moved in to break down the edge of the upper, stiffening, 8m, and the upper is then secured to the insole by tacks driven by any suitable tack-driving device. The breakdown-irons having been moved backward out of the way, the pressing D is then brought into use to fit, mold, level, and compress the folded-in and fastened edge of the upper, lining, stiffening, &c., to and upon the outsole. This compressing or conforming iron is shaped upon its under surface, preferably, to substantially conform to the level of the last, and its edge conformation is substantially parallel with the edge of the last. It is represented as supported by the post (1, extended in from the cross-head d, and the cross-head is given a vertical movement by means of the rods d" (P, pivoted at d d to the lever dflwhich is in turn pivoted at d to the base a.- This lever is adapted to be used as a foot-treadle, and it has at its outer end the pivoted footsupport d By this leverage we are enabled to bring the iron down upon the work with considerable pressure, and forcing the turneddown upper at its edges down and against the iron band, and we operate the device immediately after the breaking-down irons have been withdrawn, but while the band still and holds the upper to the surface of the last; it will be seen that .by this operation not only is the edge of the upper and the parts thereof made to smoothly fit the insole; but the pressure exerted thereon along the corner of the last causes the upper to be pressed against the inner surface of the band, so that a very perfect and symmetrical corner is obtained. In fact, the corner of the upper submitted to the action of the band and presser may be said to be molded to shape, and this gives a very perfect shape to this section of the upper, and in an easy and expeditious manner. It is of course desirable that the last-pin shall have a vertical movement in order that the position of the work may be determined and brought to the same level in relation to the breaking-down-irons and the band, and it is desirable that this adjustment of the last be made automatic as nearly as possible. To accomplish this end, we have arranged the lastpin E upon the post 6, and have supported the post in the hole 6' in the blocke upon the yielding cross bar or rod ef,,th.is -eross bar or rod being suspended by the springs 0 a This .provides the post with a vertical movement.

It is necessary, however, that; it should be locked automatically in place after it has been adjusted, and this'weaecomplish by forming time developing a square V upon the back surface of the post 6 the teeth F, and by arranging in the block c a lockingblock, f, having teeth f the the teeth F, which is moved automatically .upon being released, so that the teeth f shall close upon the teeth F; and'this automatic locking is provided by means of the springs f When the pin is in its highest position, it is necessary of course that it shall be unlocked, anditis of course essential to release the locking-bolt, so that the pin shall be locked before the breaking-down irons are moved inwardly, or, in fact, before the band 0 is closed upon the last. To accomplish this,we employ a catch, j, which hasthe wedge-shaped end f, adapted to close upon the incline f of the block f. This catch f is connected by means of the arm 6 with the sliding sleeve f, carrying the cam or incline b. By this arrangement it will be seen that upon the least downward movement of the sliding sleeve f the point f t of the catch is immediately withdrawn from the recess f and the block is at'liberty to close automatioally upon'the jack-post. Upon the upward movement, however, of the sleeve the incline on the end of the catch comes in contact with the incline on the latch and moves it back automatically to engage the teeth f from the teeth F.

In the operation the last is placed upon the last-pin, and the last-pin is moved downward until the insole has been brought to a proper level, when, by placing the foot upon the treadle to operate the device and slightly depressing it, the post is automatically locked. To determine what shall constitute the proper height or level forthe, insole, there may be employed an insole-gage consisting of the plate G, carried by a rod,-g, and dep nding from the arm 9, which is pivoted at ya so that the plate may be swung over upon the insole after the shoe and last have been placed upon the spindle or pin, and the upper surface of the insole is brought to the level of the lower surface of this gage-plate G. Of course, it is obvious that upon the upward movement of the catch f a the latch is withdrawn from the jackpost and the pin automatically lifted to its original position.

In operating, the last with theupper and insole mounted thereon is placed upon the jack-pin and the gage swung over and the last depressed to the proper level. Upon the downward movement of the treadle the last-pin is immediately locked, the band C brought to hear at the heelend, and caused to conform to the sides of the last and to the shank. The breakdown-irons are then operated to turn in sections of the edge, and the sections of the upper between the breakdown-irons are turned down and fastened. The breakdown-irons are then withdrawn. The compressor is then brought into use, and the upper madesmooth, consolidated, and finished. The compressingiron is then removed, the band thrown back, the last-post released, and the last removed from the pin.
